Edit: The Jasper Joke.
orb: Scalp skill & Electrification (5) set + Jasper =
shield: Scalp skill & Electrification (1) set. replace Electrification with Momentum.
shield: Scalp skill & Momentum (1) set + Jasper =
orb: Time Warp skill & Momentum (5) set. how did I get Time Warp?
Hatchet: Scalp skill + Jasper =
Bracer: Time Warp skill
Jasper changes an item and it's skills, and most class specific affixes, to the new classes skills and affixes. when I Jaspered the orb to shield, the Scalp skill stayed the same, as Scalp is a Warrior skill. but since Scalp is normally on Hatchet, when you use Jasper on Hatchet, it changes to Bracer, which has Time Warp. so when I Jaspered the Shield with Scalp back to Orb, it changed Scalp to Time Warp.
I was a little confused at first, because I had never read about this in the Forums, but I had read enough to do the research to figure this out, so it only cost me a few more crystals to return the Time Warp back to Scalp.
